Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sheet type multi-layer ceramic capacitor electroplating collection, in particular to an electroplating collection device for MLCC. BACKGROUND

[0002] With the rapid development of electronic information technology, as one of the three electronic components, multi-layer ceramic chip capacitors (MLCC) are constantly developing towards miniaturization, high capacitance, high frequency, etc. MLCC is formed by stacking internal electrodes arranged in a staggered manner between left and right, sintering at high temperature to form a ceramic chip, and then sealing metal external electrodes at both ends of the chip to form a structure similar to a monolith.

[0003] In the production process of MLCC, rolling plating lines are used for electroplating of medium and large products. Since the rolling screen electroplating is basically large capacity and large volume products, the screen discharge operation after product electroplating is relatively inconvenient. In patent CN115806205B, the products and accompanying plating products (such as zirconium balls) in the rolling screen are discharged into a steel screen in a water tank by rotating the rolling cylinder and adding water washing, and then the steel screen is carried to a fixed discharge area by the staff to separate the products and the stirring zirconium balls. Since the product volume is large, the product will collide with the accompanying plating product during separation in the discharge area, resulting in ceramic damage. UTILITY MODEL CONTENT

[0004] Therefore, the present application provides an electroplating collection device for MLCC, which can solve the above technical problems, improve the ceramic damage of MLCC products during rolling plating, and improve the screen discharge efficiency.

[0008] A collection tank is provided at the bottom of the water tank, and a collection port is formed above the collection tank. The bottom of the collection tank is provided with a second horizontal moving part, and the second horizontal moving part cooperates with the first horizontal moving part to enable the collection tank to move horizontally at the bottom of the water tank.

[0009] A filter screen is provided on the collection port of the collection tank to separate the accompanying plating products.

[0010] In one exemplary embodiment, it further comprises:

[0011] A support frame is installed in the material receiving port; an inner side of the support frame forms an embedding slot, and the frame of the filter screen is installed in the embedding slot.

[0012] In an exemplary embodiment, further comprising:

[0014] In an exemplary embodiment, the embedding slot, the frame of the filter screen and the pressing frame are respectively provided with fastening holes for being locked by fasteners.

[0015] In an exemplary embodiment, the bottom of the material receiving slot is provided with a first drain hole;

[0016] The material receiving slot is further provided with a filter cloth, the filter cloth shields the first drain hole, and the filter cloth is used for separating MLCC.

[0017] In an exemplary embodiment, the filter cloth is in a groove type and covers the bottom surface and the side surface of the material receiving slot.

[0018] In an exemplary embodiment, the first horizontal moving part is a guide element, and the second horizontal moving part is a sliding element.

[0019] Alternatively,

[0020] The first horizontal moving part is a sliding element, and the second horizontal moving part is a guide element.

[0021] In an exemplary embodiment, the guide element includes two guide rails arranged in parallel, and the sliding element includes a sliding groove corresponding to the guide rails.

[0024] The present application has the following beneficial effects:

[0025] The electroplating receiving device for MLCCs disclosed in this application features a receiving trough at the bottom of the water tank used for receiving electroplating drums, and a filter screen above the receiving trough for separating MLCCs and MLCCs to be plated. This ensures that both the MLCCs and MLCCs being received from the electroplating drums fall onto the filter screen. A horizontal moving component allows the receiving trough to move horizontally at the bottom of the water tank. During this movement, water flow ripples the MLCCs, causing them to pass through the filter screen and fall into the receiving trough. This effectively separates the MLCCs from the MLCCs after the electroplating process, improving receiving efficiency. Furthermore, the MLCCs and MLCCs in the water are not damaged by collisions, thus improving product yield. This application also facilitates filter screen replacement to separate MLCCs and MLCCs of different sizes. Additionally, this application includes a double filter screen, further simplifying the separation of MLCCs and MLCCs of different sizes. Attached Figure Description
